MEANS FOR GENERATING GAS AND WATER-VAPOR FOR HEATING, &c.

SPECIFICATION forming part of Letters Patent No. 642,633, dated February 6, 1900.

Application filed May 18, 1899. Serial No. 717,329. (No modeL I T0 at whom it may concern:

Be it known that I, JOHN P. B. SADTLER, a citizen of the United States, residing at Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Means for Generating Gas and Water-Vapor for Heating and Like Purposes, of which the following is a specification.

This invention relates to means for burning gas and water-vapor; and it consists in supplying a gas or similar burner capable of discharging a flame downwardly with a body of water the surface of which is exposed to the flame, so that combustion of air, gas, and water is produced at'substantially one and the same point and in close proximity to the water-surface, and the heat from said combustion rises through the source of the flame, thus greatly intensifying the heat and delivering it in a direction opposite the course of the flame, whereby the full benefit of the simultaneous combustion of the two vapors in one flame is realized and the entire heating capacity thereof utilized.

All vapor burners or gas-heaters known to me which utilize water employ it for moistening the products of combustion, for injectingjets of steam into the flame or the latter into the former, and for changing the color and character of the flame. Such burners or heaters either have a water-gutter around the burner, a water-tank located in the center of a ring-burner and extending above and below the ring, the walls of said tank separating the water from'the flame, a water-tank suspended below the bur'ner with cold air directed upon the surface of the water and the flame going in the opposite direction (as in all the above-noted burners) to the surface of the water, or a water-wick projecting into an upwardly-burning flame, with the heat discharging in the same direction with the course of the flame.

The object therefore of my invention is to form a combustion of air, gas, and water-vapor upon approximately the surface of the water from which the vapor is derived and to conduct the heat from said combustion through the source of the combustion-flame in the opposite direction to the latter.

My invention may be eifected with any of the well-known burners, such as are capable of burning upside down, by simply giving them this position, so that the flame will project downwardly and by providing them with means for holding a body of water exposed to the downwardly-shooting flames; but the best results are attained bya special and preferred device hereinafter to be shown and described.

In the accompanying drawings, forming part of this application, Figure 1 is a side elevation of a burner embodying my invention. Fig. 2 is a central vertical sectional view of Fig. 1 through the water-cup and stem. Fig. 3 is a detached top view of the water-receptacle. Fig. 4 is a central vertical section of a modification showing an ordinary gas-burner with legs which hold a water-basin. Fig. 5 is a central vertical section of afurther modification, showing my device applied to a heating-stove. Fig. 6 shows a heating-drum attached to the burner.

The same numeral references denote the same parts in the several figures of the drawlngs.

The burner employed to carry out my invention is one having a gas-chamber 1 and overlapping tubes 2 and 3. I provide this burner with ears or lugs 4 about its periphery and a depending flange 5, having an opening covered by a slide 6 for the purpose of igniting the gas. The water-receptacle 7 is of the same size and form as the burner and has a series of air-ducts 8 extending through the body of water 9, held by the receptacle and terminating above the surface of the water, so that the cold air-is not directed upon or toward the water. The periphery of the receptacle is provided with projections 10 for the purpose of securing the receptacle to the burner by means of suitable bolts and the ears or lugs 4.

The receptacle 7 has a stem or neck 11, which is provided with a cup 12, whence water is supplied through the said stem or neck to the receptacle. The water in the cup will indicate the height of the water in the receptacle, so that the water in the latter may not become exhausted.

It will be observed that the space between the burner and the receptacle constitutes a the flame of such combustion, the inner of.

said tubes acting as the heat-discharge instead of air-ducts, as is the case when the burners hereinbefore referred to are operated in the ordinary way-that is, without being.

turned upside down and not in combination with a body of water. An ordinary burner is shown in such position in Fig. 4;, the burner 13 being provided with legs 15, having lugs 1 for supporting a pan 16, containing a body of water the surface of which is exposed to the flames from the burner and the inner tubes 17 of which act as heat-conductors.

Fig. 5 shows my vapor-burner applied to an ordinary heating-stove 18, and the same may be applied to a gas-heat radiator, to a range or boiler, and in the combustion-chamber of a furnace with the same results as above noted.

Fig. 6 shows a heating-drum 19, riveted at 20 to the outside of the burner 21, and the water-receptacle 22 has short stove-like legs 23, thus producing a simple and complete heater.

I do not wish to be understoodas limiting myself to any particular construction of burner nor to any particular device for producing combustion ofair, gas, and water-vapor by projecting the flame downward from the point of combustion and directing the heat from such combustion upward, as I desire to reserve to myself the right to apply a body of water to a gas or vapor burner, so that the surface of the water is exposed and brought in such close relation to the gas and air combustion point that the water-vapor will form an equal or material element of said combustion. I also reserve the right to make such alterations as may be found necessary in applying the device to various apparatus for heating and like purposes without depart ing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters 1 Patent, is i 1. A heater having a body of water the sur-I face of which is exposed to the jets or flames from the heater, so as to create a combustion I of gas, air, and water-vapor over the water surface.

2. A heater having an inclosed combustionchamber below the gas-chamber and directing flames downwardly, and a body of water inclosed with the heater and acted upon by the said flames.

3; A heater adapted to discharge a flame downwardly, and having water the surface of which is exposed to the tip of the flame, so as to produce combustion of air, gas, and watervapor at the surface of the water.

4. A heater having a gas-chamber provided with tubes to direct flames downwardly, and a body of water situated below said chamber, so that the water is acted upon by the said flames.

5. The combination, with a gas -burner adapted to discharge a flame downwardly, and having a gas-chamber, of a receptacle containing a body of water the surface of which is exposed to saidflame, a combustionchamber formed by and between the gaschamber and the receptacle, and air-ducts through said receptacle into the combustionchamber.

G. The combination, with a gas burner adapted to discharge a flame or flames downwardly, and a flange depending from the burner, of a water receptacle having airducts and secured to the burner so as to form a combustion-chamber within said flange.

7. Thecombination, with a gas-burner having overlapping tubes, certain of which discharge .gas downwardly, and the others discharge products of combustion upwardly, of a receptacle having air-ducts and containing a body of water the surface of which is exposed to the combustion of air and gas to vaporize the Water into the flame, and a chamber formed by coupling the burner and the receptacle.

8. The combination, with a gas-burner having top and bottom openings, and adapted to discharge a flame or flames downwardly, of a receptacle adapted to contain a body of water set as to be acted upon by the flame-jets, and having air-ducts through it positioned at points between said burner-openings.

In witness whereof I hereunto set my hand in the presence of two witnesses.

JOHN P. B. SADTLER.
